Fuji X-S1 Back to $599. @ Amazon

Looks like Fuji/Amazon are out of the $349. cameras, but have some at the $599. amount. Wonder why the increase and what serial numbers are these? Pretty strange price bouncing from retail to super bargain and then back to almost retail.

I was tempted to take the plunge, but don't see much improvement (if any) in IQ over the HS35 I'm shooting. I do know everyone seems to love the EVF though.
